EXERCISING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 730,477, dated (Tune 9, 1903. Application filed September 13, 1901 Serial No. 75,350. (No model.)

' To all whom it may concern.-

Be it known that 1, MICHAEL B;RYAN, a citizen of the United States, residing at Cologne,

y The object of my invention is to supply an exercising apparatus by means of which the degree of force exerted in exercising with it can be determined, thus enabling this force to be regulated intelligently, so that, for example, it is possible for a physician to prescribe exercises involving a greater or less expenditure of force, according to the physical constitution of the person exercising.

In carrying out my invention 1 operatively connect a dynamometer to an exercising-ma: I

chine in such a manner that said dynamom eter is operated when the exercising-machine is in use. The dynamometer is provided with two indicators which move over a scale graduated in pounds and kilos. One of said indicators is moved by mechanism in the interior of the dynamometer-case, while the other can be moved by hand. A pin is fast to the indicator moved by said mechanism and engages the second indicator, moving the same over the graduations and indicating the maximum force exerted by the operator in using the exercising-machine. It will be understood that the pin on the indicator actuated by said mechanism and also the second-indicator itself may be dispensed with, if it is, not desired to indicate the maximum force exerted.

Referring to the drawings, Figure 1 repre sents an exercising-machine operatively connected to a dynamometer. Fig. 2 is a front elevation of the dynamometer. Fig. 3 is a side view of the same. Fig. 4 is a section taken on line 4 at of Fig. 3. 5 is a plan View of one of the elastic-connection cross-bars. Fig. 6 is a view similar to Fig. 1, with the elastic cord, handles, and pulleys, together with the dynamometer, reversed and the pu1- ley-block 16 suspended from the hook 43, while the eye 28 of the dynamometer is hooked into the hook 15 upon the elastic-connection cross-bar 11.

The exercising-machine is of well-known construction; and it consists of two cross-bars 29 29 in the casing 24. gages a stationary hook 4:3.

10 11, joined together by elastic connections l2 12, said cross-bars having circular holes 40 extending therethrough and a slot 41 extend ing from each of said holes to the front of the cross-bars. The elastic connections 12 12 are provided at each end with cord-caps 42,which prevent the cords from being drawn out of the holes 40 lengthwise thereof, and when it is desired to remove one of said cords from the cross-bars it is slipped out of the hole 40 through the slot 41,'and thus said elastic connections are'detachably attached to the cross- .bars 10 11, so that one or more'of said connections may be removed to reduce the resistance of the exercising-machine. By this means the force exerted in exercising is likewise reduced. The lower cross-bar 10 is provided with a hook 13, by which it is connected to an eye 14, fixed to the floor or to any desirable stationary point. provided with a hook 15, upon which is mounted a'pulley-block 16, provided with a pulley 17, arranged to rotate thereon. I An elastic cord 18, provided with handles The upper cross-bar 11 is 26, passes around the pulley 17 and thence 7 .A reciprocatory pin 27 has an eye 28 at its upper end and is arranged to slide in bearings The said eye 28 en- A spiral compression-spring 30 encircles the pin 27, one end thereof bearing against the interior of the casing 24: and the other against a shoulder 31, formed upon the pin 27, said spiral spring tending to hold the pin 27 downward.

To the lower end of the pin 27 is fastened a rack 32, which meshes a pinion 33, fast to a spindle Said spindle projects through the casing 24: and has fast thereto an indicator-finger 35, which moves on the front of the casing 24:, so that according to the degree of pulling force applied to the eye 28 or the hooks 22 the indicator 35 swings to a greater or less extent across the scale 36 upon the face of the casing 24.

In order to determine whether during exby the indicator 35.

amount, a second indicator 37 is provided,

'which is loose upon the spindle 34 and is located beneath the indicator 35. In the indicator 37 is a notch 38, which is engaged by a pin 39, fast to the indicator 35, when said indicator 35 swings to a sufficient distance therefor, and by means of said pin the indicator 37 is moved around the spindle 34 as a center, passing across the scale 36. Upon the return movement of the indicator 35 when the tension of the exercising-machine upon the dynamometer is released the indicator 37 remains stationary and thus indicates the extreme point to which it is moved It is therefore evident that the indicator 35 will always indicate the maximum force exerted.

I have illustrated my improved dynamometer connected to an exercising-machine, with the dynamometer at the top of said exercisingmachine and the handles pulling the elastic cord 18 downwardly; but it is evident that, if desired, the elastic cord, with the handles and pulleys thereon, together with the dynamometer, could be reversed, as shown in Fig. 6, in which figure the pulley-block 16 is suspended upon the hook 43, while the eye 28 of the dynamometer is hooked into the hook 15 upon the elastic-connection cross-bar 11, without departing from the spirit of my invention.

Having thus described my invention, what 1 claim,and desire by Letters Patent to secure,

1. In an elastic exercising-machine, a dynamometer comprising a casing, two hooks rigidly attached to said casin g, a reciprocatory 1' pin provided with an eye and located in a plane between said hooks upon the diametrically opposite side of said casing from said hooks, a rotary indicator, and mechanism operated by said pin to rotate said indicator; a pair of pulleys mounted upon said hooks, a single pulley located at a distance from said pair of pulleys, and an elastic cord fittedwith handles, said cord running over said pair of pulleys to said single pulley.

2. In an elastic exercising-machine, a dynamometer comprising a casing, two hooks rigidly attached to said casing, a reciprocatory pin provided with an eye and located in a plane between said hooks upon the diametrically opposite side of said casing from said hooks, a rotary indicator, and mechanism operated by said pin to rotate said indicator; two cross-barsconnected together by elastic connections, a pair of pulleys mounted upon said hooks, a single pulley mounted upon one of said elastic-connection cross-bars, and a cord fiitt-ed with handles, said cord running over said pair of pulleys to said single pulley.

3. In an elastic exercising-machine, a dynamometer comprising a casing, two hooks rigidly attached to said casing,a reciprocatory pin provided with an eye and located in a plane between said hooks upon the diametrically opposite side of said casing therefrom, a rotary indicator, mechanism operated by said pin to rotate said indicator, and a second indicator adapted to be rotated by said first indicator in one direction, a pair of pulleys mounted upon said hooks, a single pulley located at a distance from said pair of pulleys, and an elastic cord fitted with handles and running over said pair of pulleys to said single pulley.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

MICHAEL E. RYAN.
